Abstract: The occurance of disturbance directly influences the change of landscape pattern. Human disturbance influences the changing rate and direction. With the increase of the population and the economical development, the human disturbance plays a more and more important role in landscape change. The forest landscape change also affect the activity of human beings contrarily. We analysed the landscape pattern change in the study area using a set of landscape indices. The results showed that human disturbance caused the increase of landscape diversity and decrease of forest dominance in Daxinganling forest landscape. The landscape had a fragmentation trend. Pattern change influences the environment and migration of the population. To maintain the sustainable development of the forest, rational human activity must be emphasized.
